The Environment Agency has issued a flood warning for parts of the Norfolk Broads because high tides are preventing rivers from draining into the sea.
The areas most at risk are in Reedham, Cantley and Brundall.
There is also a flood warning in force near Peterborough on North Bank Road alongside the River Nene west of Dog-in-a-Doublet Sluice.
The Environment Agency says heavy rain over the past week has caused river levels to rise on the River Nene.
During periods of high tide the river will be unable to discharge into the sea, resulting in tide lock conditions. This is likely to lead to localised flooding at North Bank Road. Whilst the Flood Warning is in force, the Local Authority will close North Bank Road.
There are a number of lower level flood alerts in force across the Anglia region
